Abstract

Biofuel saat ini menjadi salah satu aspek utama dalam bidang penelitian. Hal ini dikarenakan ketersediaan bahan bakar fosil yang semakin langka, namun konsumsi energinya semakin meningkat. Oleh karena itu, penelitian mengenai pre-treatment pengolahan limbah sebagai sumber karbon organik dirasa perlu untuk dilakukan agar dapat menghasilkan karbon organik yang selanjutnya dapat diolah menjadi biofuel. Percobaan ini bertujuan untuk mengetahui kinerja terbaik campuran fungi Trichoderma viride dan Aspergillus niger terhadap biological treatment tempurung kelapa serta pengaruhnya terhadap kuantitas dan kualitas sumber karbon organik (dalam hal ini glukosa). Penelitian ini diawali dengan proses steam-treatment pada kondisi optimum operasi pada penelitian sebelumnya (Arias, 2011) yaitu waktu 10 menit tekanan dan steam 2 bar, penambahan 2% H2SO4, dilanjutkan dengan steam treatment pada 210°C selama 5 menit. Setelah steam treatment, kemudian dilakukan biological treatment menggunakan jamur Trichoderma viride dan Aspergillus niger dengan konsentrasi campuran fungi sebesar 20% (v/v) dan variabel rasio Trichoderma viride : Aspergillus niger sebesar 0:1, 1:0, 1:2, 1:3, 2:1, 3:1 (v/v). Proses biological treatment dilakukan selama 10 hari (sampai kadar glukosa konstan). Dari hasil penelitian didapatkan kadar glukosa terbaik sebagai sumber karbon untuk produksi biofuel terdapat pada kondisi rasio A.niger dan T.viride sebesar 1:2 (v/v) selama 96 jam dengan yield glukosa sebesar 41.168% (24.873 g/L) dan rasio A.niger dan T.viride sebesar 2:1 (v/v) selama 96 jam dengan yield glukosa sebesar 40,349% (24,378 g/L)

Nowadays, biofuel is become one of the main aspect of the research. It is caused by the imbalance between the availability of fosil fuels in the world and the increasing of energy consumption. Because of that, the research on pre-treatment of waste treatment as the organic carbon resource has an urgency to be done, so it can produce the organic carbon that will be treated furthermore to be a biofuel. The objective of this research is to define the best effect of Trichoderma viride and Aspergillus niger mixture to the biological treatment of coconut shell and also the effect to the quantity of organic carbon resource (in this case is glucose). This research was started by steam-treatment process, in the optimum operating condition from the previous research (Arias, 2011) at 2 bar steam pressure (pre-steam-treatment) during 10 minutes, the addition of 2% H2SO4, continued with steam treatment at 210°C during 5 minute. After steam treatment, then the biological treatment using Trichoderma viride and Aspergillus niger were added by 20% (v/v) concentration of fungus mixture and the variables of mixture ratio Aspergillus niger : Trichoderma viride were 1:0, 1:2, 1:3, 0:1, 2:1, 3:1 (v/v). This biological treatment process was done in 10 days (until glucose contains being constant). From the research results, it reports that the best amount of glucose as organic carbon source for biofuel production was A.niger and T.viride ratio 1:2 (v/v), during 96 hours with glucose yield of 41.168% (24.873 g/L) and A.niger and T.viride ratio 2:1 (v/v), during 96 hours with glucose yield of 40.349% (24.378 g/L)
